Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a camera-integrated video recorder. (Background of the Invention) A conventional camera-integrated video tape recorder directly records the video signal of a subject photographed by a video camera on a video tape. It was recorded on a recorder.

Therefore, it has been difficult to image-process and record external data and the like at the same time as the video signal depending on the purpose.

(Object of the Invention) The present invention solves these drawbacks and provides a camera-integrated video recorder that can image-process a video signal from a video camera simultaneously with a signal from an external device and record the processed signal. The purpose is to

(Example) An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an explanatory diagram of a camera-integrated video recorder. A camera-integrated video recorder 1 shown in FIG. 1 includes at least a photographing lens 2, a video camera circuit 3, a video tape recorder 4, a switching circuit 5, an output terminal 6, an input terminal 7, and a changeover switch 8. The video camera circuit 3 outputs a video signal of a subject and the like.

The video tape recorder 4 records video signals and the like of the subject. The switching circuit 5 is an electric circuit having a switching function, and is schematically referred to as A in this embodiment.

It has B and C terminals. The output signal of the video camera circuit 3 is output to the A terminal of the switching circuit 5 through a signal line a. The input signal of the video tape recorder 4 is passed through the signal line d via the C terminal of the switching circuit 5.
recorded through. Output terminal 6 is switching circuit 5
It is connected to the A terminal of the video camera circuit 3 by a signal line, so that the video signal etc. of the video camera circuit 3 can be outputted to the outside. The input terminal 7 is connected to the B terminal of the switching circuit 5 by a signal line C, and is configured to be able to input a video signal or the like from the outside. The changeover switch 8 connects the switching circuit 5 and the signal line e.
The switch 8 is configured to connect the A terminal and the C terminal or the B terminal and the C terminal in the switching circuit 5, and the changeover switch 8 connects the external device adapter 9 and camera unit. It is automatically switched when the body type video recorder 1 is attached or detached. The adapter 9, which is an external device, is configured to generate a still image such as a title, date, etc., combine it with a video signal from the video camera circuit 3, and output the synthesized image. The adapter 9 includes a connector 10 and a signal processing circuit 12, and the signal processing circuit 12 connects the video signal from the video camera circuit 3 and the title,
This is to synthesize a still image signal such as a date. When the adapter 9 is attached to the camera-integrated video recorder 1-, the connector 10 sends the video signal output from the output terminal 6 to the signal processing circuit 12, and then the signal processing circuit 12
A composite signal (video signal) output from the input terminal 7 is transmitted to the input terminal 7. Further, the connector 10 is configured to change over the changeover switch 8.

The operation of the embodiment will be explained below. When no external device is attached to the camera-integrated video recorder 1 shown in FIG. A video tape recorder 4 is directly electrically connected. Therefore, in this case, the video camera circuit 3
The video signals and the like are recorded on the video tape recorder 4 as they are.

Next, the camera integrated video recorder 1 (hereinafter, integrated V
For example, consider a case where an adapter 9 having a signal processing circuit 12 capable of inserting a caption or characters is attached to a TV (abbreviated as TR). Detecting that the connector 10 of the adapter 9 is connected to the output terminal 6 and the input terminal 7 of the integrated VTR 1, the changeover switch 8 switches the switching circuit 50.
Cut off the connection between the A terminal and C terminal, and switch to the connection between the B terminal and C terminal. Therefore, at this time, video signals etc. from the video camera circuit 3 are sent to the output terminal 6 through the signal lines a and b, and from the output terminal 6 to the adapter '9.
The signal is sent to the signal processing circuit 12 via the connector 10 . Therefore, image processing such as date, data, and screen processing can be performed as intended by the photographer. Then, the image-processed composite signal (video signal) is passed through the output terminal 11 to the integrated V
The signal is sent to the input terminal 7 of the TR 1 and input to the video tape recorder 4 through signal lines c and d, and the combined signal is recorded on the recorder 4.

Although the present invention has been described above with reference to the illustrated embodiments, the present invention is not limited to the above embodiments. For example, if a small monitor is attached as an external device to the output terminal 6 of the integrated VTR 1, shooting People other than the user can view the shooting status.

Of course, at this time, nothing is connected to the input terminal 7, and the changeover switch 8 is not operated, so that the switching circuit 5 maintains the connection between the A terminal and the C terminal. In this way, it is possible to record a recording that includes the shooting intentions of the two people.

Additionally, if the camera is equipped with an optical viewfinder, it is effective to use a small monitor (such as an electronic viewfinder) to check the recording status to see if the video is being recorded properly.

Furthermore, it is also possible to attach an external device to the integrated VTR 1, such as to connect another video camera. At this time, terminals of an external device are connected to the output terminal 6 and input terminal 7 of the integrated VTR 1, and the B terminal and C terminal of the switching circuit 5 are connected by the changeover switch 8.

Two video cameras can take pictures of different subjects at the same time, or they can take pictures of one subject at the same time. For example, if you want to take pictures of different subjects, use an external device to
If the configuration is such that one of the video signals from the two video cameras can be selected, one can be recorded according to the photographer's intention. For example, when taking a picture of one subject, one camera takes the picture from the front, another camera takes the picture from the side, and an external device transfers video signals from 92 video cameras to half of one screen facing the front. Three-dimensional photography becomes possible by processing the image so that it can record the image from the front and the side image from the remaining half. Therefore, if the external device has various image processing functions, you can use the integrated VTR to record various types of data.
It can be easily done with.

(Effects of the Invention) As described in detail above, according to the present invention, the camera-integrated video recorder can temporarily output the video signal from the video camera to the outside, and the video signal can be transmitted to the external device. It is configured to perform image processing and input the processed external output signal to the video recorder again for recording. Therefore, the photographer can easily perform the image processing desired by the photographer while taking pictures and record the images at the same time. In addition, by changing various external devices, it is possible to record images with a wide variety of variations, and in this case, it is possible to overcome the drawbacks such as deterioration in image quality caused by dubbing. 1 is a plan view of a camera-integrated video recorder showing one embodiment of the present invention.
